Actually a local weatherman said he NEVER saw mph of more than 100. It was a large system but low wind speed and the prediction by NHC’s storm surge of 18-20’ was off. You are right 12-15’ storm surge. Also, Dr. Neil Frank always said this system would go in east of the NHC’s track.
They should have listened to Dr. Frank or at least referenced him along with the NWS. The movement to the east saved Galvestion and Houston from the full storm surge. The lack of the additional 8 - 10’ surge made a huge difference.
Ah - Dr. Neil Frank is usually right on.
